Active and inactive QoS configurations
While checking for consistency of a logical interconnect with its associated logical interconnect group, the compliance of inactive QoS configurations is also checked. However, inactive QoS configurations are not visible in the UI. Even if active QoS configurations are the same between a logical interconnect and an associated logical interconnect group, because of inconsistencies in inactive QoS configurations stored internally, a logical interconnect consistency status can appear as Inconsistent.
Perform an Update from group to bring the logical interconnect group and the logical interconnect into a consistent state.
QoS configuration types
The following QoS configuration types are available:
- Passthrough
All ingress packets are not classified at egress. FCoE packets having a separate PG (Priority Group) are processed at ingress. There are no traffic classes, maps, or rules applied. Passthrough mode is equivalent to no QoS (QoS disabled).
- Custom (with FCoE lossless)
Enables QoS and allows a customized configuration that includes FCoE class. The configuration defines two default system classes, Best Effort and FCoE lossless. You cannot edit the FCoE Lossless class and it is preconfigured for 50% bandwidth of the port. You can also configure up to six additional classes for non-FCoE Ethernet traffic.
- Custom (with RoCE lossless)
- Enables QoS and allows a customized configuration that
includes RoCE class. The configuration defines two default system
classes, Best Effort and RoCE
lossless. The RoCE lossless class is preconfigured for
50% bandwidth of the port.
You can edit the bandwidth for the downlink ports as part of the DCBX configuration. You can also configure up to six additional classes for non-RoCE Ethernet traffic.
- Custom (without FCoE or RoCE lossless)
- Enables QoS and allows a customized configuration without FCoE. The configuration defines one system class, Best Effort. You can configure up to seven additional classes for non-FCoE or non-RoCE Ethernet traffic.
